Could an album have been more prophetically titled than Kacey Musgraves' "Golden Hour," a country-music outlier that picked up Album of the Year at the Grammy Awards, the ACM Awards and the CMA Awards, making it one of only three albums to win all three?

A week after pulling it off, she played Coachella, the first appearance by a female country artist at that festival, where she playfully scolded the decidedly non-country crowd for jumping the gun and shouting "haw" without a prompt on her "When I say 'yee,' you say 'haw'" chant.

This Tuesday, Musgraves brought her Oh, What a World: Tour to Phoenix for a much-anticipated sold-out show at Comerica Theatre that felt like a victory lap for a singer whose previous Valley appearance was a sold-out show at the Van Buren six months earlier. .

It's been six years since Musgraves scored a most unlikely Top 10 entry on the country charts with a platinum single called "Follow Your Arrow," an ode to being true to who you are with a singalong chorus of "Make lots of noise / Kiss lots of boys / Or kiss lots of girls / If that's something you're into."

She's been following that arrow ever since. Musgraves is one of her generation's most distinctive voices, both in terms of what she has to say and her actual singing voice, which is gorgeous and sounded amazing in Phoenix as she treated fans to highlights of three albums packed with classics, from "Follow Your Arrow" and "Merry Go Round" to "Rainbow," one of 13 songs she and her bandmates dusted off from "Golden Hour."

Musgraves set the tone for Tuesday's show with "Slow Burn," the opening track of her latest release, which proved a haunting introduction whose dramatic possibilities were underscored by the star, who was strumming acoustic guitar, and her bandmates performing while backlit.

After following through with a wistful "Wonder Woman," Musgraves took a moment to address the crowd.

"OK, this is a few more people than were here last time for me," she said, with a smile.

She thanked the fans for selling out the room and talked about how much she loves this city, saying she wanted the fans to just let loose in part because their energy could help her bring her A game to the table.

"We've been going really hard," she said. "And we're nearing the end of this run. And I'm feeling a little low on energy today. And the best thing about coming somewhere like this is the beautiful energy exchange where you can give me all of your excitement, all your feels, and that's gonna pretty much just (expletive) supercharge us up."

Before returning to the music, the politically outspoken country maverick (who made headlines for speaking her mind on mass shootings at Lollapalooza after what happened in Dayton and El Paso), added, "I think there's too many reasons right now in this modern world that we can all find to disagree with each other and that doesn't have to happen tonight."

Apparently, that energy transfusion worked because Musgraves proved an engaged and engaging presence for the length of her performance, looking as radiant as she sounded in her green fringed outfit with her bandmates dressed in matching suits.

She even joked about what happened at Coachella before dusting off her “yee haw” chant. “With all these cowboys, you should be pretty good at this,” she said. “I tried it in California and it didn’t work.”

Her bandmates gathered around her bluegrass-style at the front of the stage for acoustic performances of a few of her more country-flavored numbers, including a heart-tugging "Mother," a bittersweet "Oh, What a World," a spirited "Family is Family" and "Love is a Wild Thing," which kicked into a full-band treatment for the final verse and chorus.

"Velvet Elvis" built on that momentum before giving way to a crowd-pleasing cover of Gloria Gaynor's disco hit "I Will Survive" that proved both refreshingly faithful and a surprisingly comfortable fit for Musgraves' whole aesthetic.

Following through with a suitably haunted rendition of "Space Cowboy" and "Follow Your Arrow," she stripped it down to piano and vocals for "Rainbow," which certainly felt like the concert's emotional climax (although a heartfelt "Mother"did come awful close), after telling the fans how much their continued support has meant, "especially being an artist that really doesn't get played on the radio that much."

Then it was back to the dancefloor, bringing the night to a rousing conclusion with two disco-flavored gems, the Brooks & Dunn song "Neon Moon," which Musgraves definitely made her own, and "High Horse," which had fans jumping up and down.

By the end of her performance, it was easy to see how the singer has managed to reach across the aisle and speak to fans who wouldn’t know if country radio is playing her new single while also proudly honoring her country roots. And that may be the best thing country music could’ve hoped for in 2019.
